Collection: Hardened Security Chain

Hardened Security Chain is the backbone of high-security applications where brute force and cutting tools are a constant threat. Ashley Chains manufactures industry-grade hardened security chain engineered from heat-treated alloy steel for maximum resistance to sawing, cutting and impact. Designed for securing motorcycles, commercial gates, plant machinery and perimeter locks, these chains combine compact link profiles with precision heat treatment to deliver a high strength-to-weight ratio without compromising flexibility.
